2/27 Cubs Saturday notebook

Angel Guzman, sidelined because of discomfort in his right shoulder, will try to test his arm on Sunday with a throwing session. Guzman already was slowed this spring following arthroscopic knee surgery in January.

* Ted Lilly did some running and played catch in the outfield Saturday. He missed five days because of the flu and a 103-degree temperature.

* Xavier Nady continued his throwing program with pitching coach Larry Rothschild. The outfielder is working on his mechanics after undergoing Tommy John surgery on his right elbow last July. Nady isn’t sure if he’ll be ready Opening Day.

“I have no idea,” Nady said. “I couldn’t tell you. The way I look at it, you have five or six weeks left. … Right now, who knows how I’ll feel [by Opening Day]? Hopefully, I don’t experience any setbacks. We’ll see.”

* Aramis Ramirez chose to sit out the live BP session vs. Carlos Marmol on Saturday. Starlin Castro took his turn and got plunked in the backside by one of Marmol’s sliders.

“He didn’t leave — he stood there, to his credit,” Lou Piniella said of Castro.

Ramirez doesn’t like live BP, preferring to hit in the cages or off the coaches.
